A common way to dry clothes is tumble drying. Electrolux is one of the world leading manufacturers of household appliances and currently is working on a heat pump tumble dryer product. This master thesis is a study of the aerodynamic properties for the internal air flow for the mentioned heat pump tumble dryer. If press

Årligen dyker rapporter upp om hur klimatförändringar förändrar vår värld. Stigande havsnivåer och kraftigare skyfall skapar redan idag problem runt om i världen, och Skånes låglänta kuster är speciellt utsatt i en svensk kontext. Hur ska kommuner i Skåne hantera det faktum att stadsdelar inom en snar framtid kan komma att drabbas av översvämningar flera gånger per år? Har de verktygen för att hanFloods are expected to increase around the world due to climate change, and Scania is especially vulnerable with its elongated coastline and lack of postglacial rebound. Spatial planning has a key role in adapting to these changes and coping with the consequences. This report aims to map out challenges when dealing with flooding in the field of spatial planning in already developed areas and to pr

This study examines attitudes towards Swedish immigration and minority groups in Sweden among social work students and law students at Lund university. Firstly, this study examines if there are similarities and differences in attitudes among the students by using univariate analysis. Secondly, this study examines if there are any correlations between attitudes and the following variables: age, gen

Stadsmiljö skiljer sig från det ursprungliga landskapet, som till stor del har lämnats orörd av människan. När mer och mer mark används till att bygga städer eller för att odla mat kan det skapa problem för pollinatörer, då de är anpassade till den naturliga miljön. Pollinatörerna kan däremot ofta överleva inuti städer i parker, rabatter och trädgårdar. Det är viktigt att bevara pollinatörer, då oRecent decline in wild pollinators have been reported and studies have found a connection to increasing urbanisation, larger homogenous landscapes and increased pesticide usage. The pollinators are important to preserve for various ecosystem services, such as plant reproduction, however the effects on pollination success has not been thoroughly studied in relation to urbanisation. In this study th

Most studies done on Drosophila are made in labs and focus on genetics, something which has formed a somewhat one-sided field of studies. To counter this bias, this report was based on fieldwork. From a classical ecological aspect, Drosophila populations in southern Scania were investigated in order to put more clinical Drosophila insights in a proper context. According to previous studies, urban

Genetically modified maize, can it be trusted? In a world with a constantly growing population there is a need to find a way to cultivate enough food for everyone and one of the things that might help with that is genetically modified crops. Genetic modification means that a trait has been given to a plant that it does not normally have. These traits can be resistance to a pest, disease or an her

The Bumbling Bumblebee, they see more than you think! Bumblebees are probably one of the most universally loved insects in the animal kingdom. They don’t irritate you or sting you unlike their relatives, instead they do their own thing while performing their daily tasks of collecting pollen and nectar for the colony. We wanted to learn more about how the bumblebee view the world and how the envir

The Internet, which is the most important component of digitalization, has proved to be a useful, but unfortunately economically difficult channel for the news agency. The rapid shift of digitalization in the 21st century has changed the game plan for traditional fashion journalism. Editors have, through various strategies at the best of their ability, adapted to the new market situation and large

Bird flu: Tracking the virus It is estimated that a whopping 55 million chickens are eaten every day worldwide. They are a main source of proteins in many corners of the world. In developing countries, 20% of all consumption of protein stems from chickens. The industry is dependent on keeping the poultry healthy and safe for consumption. This huge task involves the suppression of natural phenomen

Doftreceptor Or22a och dess betydelse för äggläggning hos bananflugor Vanliga bananflugor har länge använts som testorganismer inom biologisk forskning, så som neurobiologi. Anledningen till detta är att de har ett nervsystem som är lättillgängligt men enklare uppbyggt än däggdjurs (Stocker, 1994,). Luktsinnet hos bananflugor sitter i antennerna och i de maxillära papillerna, som sitter vid flugaThe fruit fly Drosophila melanogaster has a well-studied olfactory system. A crucial part of the olfactory system is the olfactory sensory neurons (OSNs). One type of these OSNs, Ab3a, expresses the Odor receptors (ORs) Or22a and Or22b. Or22a is known to play an important role for behaviors like oviposition, but no strong ligand has been found for Or22b. Recent studies have shown that D. melanogas

Applications based on Wireless Sensor Networks are making their way into all kinds of industries. Today, they can do anything from off-loading hospitals by monitoring patients in their homes to regulating production lines in factories. More often than not, they perform some kind of surveillance and tracking. Thus, in most cases the information they carry is sensitive, rendering good encryption sch

The main objective of this Master Thesis is to upgrade 16x8 interrupt controller and priority resolver to 128x8 input interrupt lines and adding a debug feature for this customised processo

Wing pigmentation in dragonflies and damselflies (odonates) functions as a secondary sexual trait with a role in courtship and antagonistic male-male interactions. Recently, a thermoregulatory function of wing pigmentation has also been suggested. This study aimed to elucidate how both sexual and natural selection have influenced the evolution and global distribution of wing pigmentation in odonat

Sponges are aquatic filter feeding animals that use internal chambers comprised of choanoflagellate-like cells called choanocytes to pump and filter water. In this study I investigated the behavior of choanocytes in juvenile Amphimedon queenslandica, a coral reef demosponge, when they were fed Photobacterium damselae subsp. damselae compared to when they were maintained in 0.22μm filtered seawater

Diploid potato cultivars that are propagated by True Potato Seeds (TPS) are a new potentially revolutionary way of potato breeding. Conventional breeding is based on highly heterozygous tetraploid potato varieties. Diploid potato breeding by TPS is useful to create inbred lines and from there hybrid offspring. TPS is cheaper, has almost no diseases and is easy to distribute. Diploid potatoes have Are potatoes, grown from seeds, the future? Did you know that you can grow potato plants from seeds? A potato plant has two ways to propagate itself; by the all known potato that we love to eat and by seeds that are grown in tomato-like berries above the ground. These seed producing potato plants that are as well diploid (two copies of every chromosome) instead of conventional tetraploid (4 copie

It was in the early 1980s when Peter Ryan from the University of Cape Town started investigating ecological and conservational factors surrounding the endemic Nesospiza finches in the Tristan da Cunha archipelago, a curious case of resource-driven bird diversification in the Southern Atlantic. Ryan and others suggests for the radiation of Tristan finches to have happened around 400,000 years ago,

In this study, Global Positioning System (GPS)-derived tracking data were used to explore aspects of the breeding season movement ecology of an at-risk seabird, the Caspian Tern, in the Baltic Sea. In particular, the foraging effort, daily activity, and foraging habitat use of the terns were investigated at two breeding colonies. Data were collected during two seasons at the colony on Stenarna isl

The pipeline was tested on sequence capture data which was obtained f

Mikropartiklar är mer än 100 gånger mindre än ett hårstrå. De brukar användas som behållare för läkemedel eller för att markera enskilda molekyler. För dessa ändamål måste ytan på mikropartiklarna modifieras med olika kemiska grupper. Jag har i detta arbete undersökt olika metoder för att binda in protein till mikropartiklar. Som modellsystem valdes mikropartiklar tillverkade av plasten polystyrenMicroparticles of various sizes carrying different surface modifications have numerous technological and biomedical applications, for example to create a larger target for a molecular receptor by binding multiply ligands to the surface of the microparticle. The aim of the present work is to study how to most efficiently couple protein molecules to the surface of such microparticles. In the current

Syftet med den här uppsatsen var att undersöka satsbetoningsmönstret hos exklamativer och vad det gör för den semantiska tolkningen av exklamativen. Detta undersöktes dels genom introspektion, och dels i ett perceptionsexperiment av att-exklamativer. Resultatet av introspektionen visade att att-exklamativers betoning i vissa fall skiljer sig från som- och wh-exklamativers. Detta gäller vid signale
